Here's a PM from Surra and my reply, Since this is really good information here for everybody, I'm going to post this in the forum.

Both actually. Rewiring them made them about 10-15% brighter. So far I only have the low beams rewired, but it's pretty simple. Using a multimeter or a test light, determine which of the three wires going to the bulb is the low beam positive. What you're going to do is cut this and add in a relay at each bulb, using the power that's there to trigger the relay. Here's a good link that explains it better than I can: http://www.danielsternlighting.com/t...ys/relays.html

By swapping to a 9007 bulb, you gain another slight brightness increase, and a little bit better spread of light to the sides as well. But you'll have to do a little mickey-ducking there. they do fit the same with one exception, two of the three locating nibs is different. Easily soved by busting the offending nibs out of the headlight housing with a flat blade screwdriver. Now both bulbs fit. The other catch is that the high beam and the ground wires have to be switched for a 9007 bulb. Here's a snip from an Audi forum about it:

"Quote"
1) Relay conversion. A must do for any of the next stages and a necesarry
precation to help protect light switch too. BUt to really protect switch
you also need to relay "parking lights of all things" because they are the
first to burn up the switch usually. Anyhow, in short, you get a relay
for the lows and one for the highs. RElays cost about $3 each for 30amp.
I found some at Shucks made by Blazer that have "DUAL" outputs to go to
the lights so you dont have to splice in a Y in your wiring. Makes it
easy. Basically, old wire from switch turns on Relay. Relay takes power
from Alternator or Battery with 12ga+ or 10ga if you go to battery. Relay
and lights are both grounded with 12-10ga to chassis. Then Power from
Relay goes to lighs Via, You guessed it, "12-10ga wire". This will give
you like 10-15% more light just by giving the bulbs the true power they
are trying to draw through 30 feet of 16ga wire. -)

2) Next step and not much harder at this point is to do a 9007 conversion.
The 9007 by a fluke of poor design has better oriented filiments for the
4kq/coupe reflector. It also just happens to be a "slightly (10w)" more
powerful bulb. To fit it knock off the bottom two tangs in your light
housing so it will fit or use a dremmel to groove the actual bulb base.
You also need to swith the ground wire and "I think" the yellow wire. I
believe it is the white that stays where it is powering the low beams.
"Of course the brown&yellow wires are really powering the relays not the
light". This makes for MUCH better lights. I think you will find them to
be at least as good as the stock lighs on your Hyandai or whatever it was.
Beyond this you may be able to find highe wattage 9007 bulbs but probably
not. BUT, YOu can get 9007 Bright Light Bulbs made by Wagner from Napa
for the same price as stock. These use a Xenon gas and emit a whiter
light and I recommend them.

Just keep in mind that our wiring won't be the same colour as theirs, so out comes the old test light again.
I am using 9007 Eurolite Fusion bulbs with relays pulling power straight from the alternator. All I can say is they are very bright. I'll see if I can take some pics comparing 9004 to 9007 to post.

BTW, Q should probably sticky this.

ill try using this info for the projector project just so happens that i just changed to 9007 and found out that i dont have any high beams will this info be any good to help this problem?

wylie-c

I do agree that the list is getting a little out of hand and could use a little ( ok, a lot ) of consolidation. I could, however just move the post into the 2nd gen mods sticky.

Big-E: You could try I suppose, but those projectors are never going to work right without the original bulbs. How did you get a 9007 in there in the first place? Are the reflector bowls just cut out for the bulbs to fit? The 9007 in a 9004 headlamp works by total fluke. Since 9007's didn't exist when our headlamps were designed, it's just pure coincidence that the newer 9007's happen to work well with our reflector and lense design. But I'm pretty sure that the engineers that design modern projectors put a lot of time and research into them, unlike the D.O.T. 9004 crap they 'came up with' to use instead of a good ol' h4 euro setup. But keep experimenting, I'd like to see if you can get both high and lows working through a single projector.

it kinda works but the low beam is really low and the high beams are like regular only if i could get sommo power to those bulbs, i was thinkin hid but i dunno what do those projectors use anyways besides xenon i got the projectors from a bmw 91' 745li it had no bulbs so i was shot to begin with well im having a lot of fun playing with these, now for the 9007 bulbs the regular low beam is like the high beams on the 9004 bulb and the high beams just dimm out because the car isint putting out enough wattage to light both so im wondering if i do this thingy with the conversion i think ill have high beams and lo beams and ill also do this to the smaller projectors thats sitting next to the large ones because i have h3's in there and they i think are on the dim side a lil..........

i really need to see pics of these setups or schematics i saw the other ones theyre good but im more of a visual learner... the head lamp wireing colore are as folows i had to figure this out when i did the h4 swap(which didnt unfortunately work), so i know the colors and stuff so here we go the lights have different colors from right to left..right side..the high beam is the orange and black, the low is the red and blue, the ground is the orange and yellow, left side....the high is the orange, the low is the red and yellow, and the ground is the green and white.

thanks for the help man!!, im just going to re wire for now, 9007 later

SurraTT

iTrader: (59)

all i need is the relays, i need 2 right low and high???

where can you get good relays??? i looked on ebay, and they are to many diff relays

max95q

iTrader: (10)

Yes consolidation is needed. I will do that this weekend.

iTrader: (14)

the switsh is made but i still dont have high beams, would i have to switsh the ground with sometin else too as stated above it did get brighter a lil bit but still no high beams thats all i want....high beams?.?.?.?.also do i need 2 relays 2 for each light or 2 for both lights?

SurraTT

iTrader: (59)

this is the relay i got http://www.radioshack.com/product.as...D226&hp=search

i only have the lows hooked up right now, tonight im going to see if its actually brighter cuz i only got left light hooked up If its better wil hoo up right



is that relay any good, its 30 amp and it says for higher automotive lighting

wylie-c

Big-E: You can use one for high and one for low, I just used one for each low because i had lots of relays. And yes, 9007's are wired differently than 9004's, that's why you have to swap two wires.

Surra: That relay should work fine.You should notice an increase in brightness. Another bonus is that you could run higher wattage bulbs now without frying the headlight switch.

Big_E-Dog

iTrader: (14)

so i should switch which wires-ground to high beam?-or ground to low beam?-or low beam to high beam?

SurraTT

iTrader: (59)

ok im going to use the same relay for high beams,

i noticed a HUGE diff already but i wont some desent blubs, how are the cool blue salvania ???? they are about $20 they also hvae some bette ones for $40 im also talking about 9007, where some good blue bulbs to get ??

also the parking light bulbs in the front i need blue ones of them but i cant find them anywhere???

wylie-c

IIRC, it's the high and ground that are the other way around on 9007's.

Ah, the good old parking lights. Sarin has some really nice super white bulbs in his. Can't remember what brand they are.

SurraTT

iTrader: (59)

IIRC??? at autozone or advance???

ohhh


PIAA Xtreme Whites in my car. $$$$$$$$$$$$$


ill just go to advance and get some



sarin where did u get the blue parking lights??????

SurraTT

iTrader: (59)

so 9007 what r the high and lows and ground, cuz when i click high it goes very dim?? i cant find a dirgiam

SurraTT

iTrader: (59)

also i got the "cool blue" they are in now fen way blue at all, so i got silverstar and they still arent blue, i guess cuz they arent getting 13 volts yet, anyone got ? these blubs

wylie-c

Cool Blue's aren't blue, neither are Silverstars. They have a Blue coating that makes them whiter, that's all. If you want some good bulbs that do shine noticeably bluer, but not to the point of being completely ricer bloo, try some Eurolite Fusion bulbs. That's what I've been using for years now, really gives it that nice HID look, and still has very good output.

http://secure.50resto.com/images/downloads/13007CD.pdf has a straightforward diagram of 9004 and 9007 wiring differences.

i do agree the bulbs are a bit lighter with the relays they give the projectors more light i think that i might install a second set of projectors so that i have high beams also what do you guys think?

SurraTT

iTrader: (59)

ive got the lights wired and i alos got 3 relays in a radioshack project boox, this is one of the best jobs ive done, pics soon, im just wating on my bulbs, they are hopefully what i wont
